Abstract :
This paper gives the analysis and design by state plane method of a current source inverter with induction motor. The basic operation of an auto-sequentially commutated current-source inverter (ASCI) connected to an induction motor load is detailed elsewhere and will not be repeated here. Each 60° period of the inverter operation with noovelap consists of three successive modes, viz charging, transfer, and single flow mode. The induction motor is modeled as a series equivalent circuit per phase but in this paper the analysis and design of a current source inverter with induction motor has been effected by a state plane method. The analytical results obtained by state plane method are compared with experimental and computed results and a good agreement between them shows the validity and effectiveness of this method
